I have also tried repeatedly but still nothing. I don't know if I expect it any time soon since they haven't said anything about Portico for any of the Windows Phone 8 handsets yet. Or at least not that I had heard of.

Ok, thank you. Wonder what I'll have to do to fix mine. When I tap "Lockscreen and wallpaper", the screen flashes and it goes back to the settings menu. :(

Go back to your backup and then redo the cab and see if it works. I put mine in Airplane mode before doing the cabs.
Also, did you put all the cabs in one shot?
I did mine one by one update, meaning from 8773 to 8779 --> 3 cab files
Then did 8779 to 8783 --> 1 cab file
Then finally 8783 to 8858 --> 4 cab files including 2 language pack (English and Spanish)

Hope this helps.

Do you think airplane mode makes a difference? I just redid it your way without airplane mode and the same thing happens (lock screen settings crashes)

Now that the Trophy has been marked for death (EOL..end of life) by Verizon, I urge everyone to vigorously tweet @Microsoft , @VerizonWireless , @HTC and @HTCUSA and "demand" that the 7.8 update be rolled out. There is power in numbers, we have a voice...use it! They can't slap us in the face like this with no penalty, there is no way that I will buy another HTC device if this is how they are going to treat it's customers.

I have two spare Verizon Trophy's and that tool linked on the front page (seven eighter) worked flawlessly to upgrade both of them. Neither are activated right now so I can't say they work perfectly fine in terms of calling/radio, however everything appears to be working in terms of the OS. I'd just go that route. It will crash in-between updates after it finishes each one, just close it and start it again. It's only after it completes so it's not dangerous.

Do we actually have anything official from Verizon in regards to the Trophy and 7.8 update? I could not find anything on their website and I did not see any mention of the Trophy officially marked EOL and no longer supported.
